Background: Compression of the left common iliac vein by the overriding common iliac artery is frequently combined with acute deep vein thrombosis in patients with May-Thurner Syndrome. We evaluate the results of treatment with thrombolysis and thrombectomy followed by stenting in 34 patients with May-Thurner Syndrome combined with lower extremity deep venous thrombosis. Material and Method: The authors retrospectively reviewed the records of 34 patients (mean age: $65{\pm}14$ year old) who had undergone stent insertion for acute deep vein thrombosis that was caused by May-Thurner syndrome. After thrombectomy and thrombolysis, insertion of a wall stent and balloon angioplasty were performed to relieve the compression of the left common iliac vein. Urokinase at a rate of 80,000 to 120,000 U/hour was infused into the thrombosed vein via a multi-side hole thrombolysis catheter. A retrieval inferior vena cava (IVC) filter was placed to protect against pulmonary embolism in 30 patients (88%). Oral anticoagulation with warfarin was maintained for 3 months, and follow-up Multi Detector Computerized Tomography (MDCT) angiography was done at the date of the patients' hospital discharge and at the 6 months follow-up. Result: The symptoms of deep venous thrombosis disappeared in two patients (4%), and there was clinical improvement within 48 hours in twenty eight patients (82%), but there was no improvement in four patients (8%). The MDCT angiography at discharge showed no thrombus in 9 patients (26%) and partial thrombus in 21 (62%), whereas the follow-up MDCT at $6.4{\pm}5.5$ months (32 patients) revealed no thrombus in 23 patients (72%), and partial thrombus in 9 patients (26%). Two patients (6%) had recurrence of DVT, so they underwent retreatment. Conclusion: Stent insertion with catheter-directed thrombolysis and thrombectomy is an effective treatment for May-Thurner syndrome combined with acute deep vein thrombosis in the lower extremity.

71 years old man was operated on due to abdominal aortic aneurysm associated with complete occlusion of left common iliac artery. The coexisting chronic deep vein thrombosis of the left femoral and iliac vein was not diagnosed preoperatively. Resection of aneurysm and Y-graft interposition was performed. Recurrent edema and pain occured to the left lower extremity immediately postoperatively, which aggrevated with the lapse of time, resulting in fatal extensive venous thrombosis. This report regards the surgical treatment and complication of the aortoiliac occlusive disease associated with chronic deep vein thrombosis.

May-Thurner syndrome is a deep vein thrombosis of the ilio-femoral vein due to compression of the left common iliac vein by the overlying right common iliac artery. Although, catheter directed thrombectomy (CDT) and thrombolysis with stent insertion has become the standard treatment method for acute or subacute May-Thurner syndrome, because of technical feasibility and lower recurrence rate, however, sometimes this methods make fatal complications. Furthermore, there are few reports on optimal treatment strategies for patients in a chronic state of May-Thurner syndrome. We now present two cases of chronic (> 1 month since onset of symptoms) May-Thurner syndrome treated by surgical thrombectomy and femoral arteriovenous shunt with simultaneous stent insertion after failed endovascular treatment. This technique may provide a significant benefit for patients who are not suitable for conventional endovascular treatment.

Cerebral dural sinus thrombosis(CDST) has been described as a rare disease with a variety of patho-etiological factors. The diagnosis of CDST is difficult due to various symptoms and signs, none of which is specific to CDST. But timely diagosis is critical for effective management. The introduction and widespread use of computed tomography(CT), magnetic resonance imaging(MRI) and cerebral angiography made early diagnosis of CDST possible. In particular, MR venography is the most useful tool for establishing a correct diagnosis quickly. In early literature, mortality ranked between 30% and 50% but in more recent series it is between 5.5% and 30%. With the advent of diagnostic and therapeutic tools, early diagnosis and proper management has made the prognosis better. The appropriate therapy for CDST, however, has been the subject of much cortroversy. Individual variations of the venous system and collateral vessels are key factors to decide the proper treatment. In this report, we present two cases with symptomatic CDST treated without open surgical or direct endovascular interventions with good outcome.

Pancreatic disease is the most frequent cause of isolated splenic vein thrombosis. Splenic vein thrombosis causes a localized form of portal hypertension known as sinistral or left-sided portal hypertension. Splenic vein thrombosis may be complicated by the formation of gastric varices, with the potential of massive upper gastrointestinal bleeding. Whereas splenectomy is considered to be the treatment of choice for symptomatic splenic vein thrombosis, the role of splenectomy in the patient with asymptomatic splenic vein thrombosis remains controversial. We report a rare case of acute pancreatitis complicated by isolated asymptomatic splenic vein thrombosis. Recognition of this disease entity is important because the risk of secondary variceal bleeding, while uncommon, can be life-threatening.

A 69-year-old man was admitted to our hospital for deep vein thrombosis, and he had experienced two episodes of left leg swelling: one happened after an 11 hour-air trip from Europe in June 2007, and the other developed 3 days after an operation for a herniated lumbar disc in July 2007. We treated him for a deep vein thrombosis of the deep femoral vein after admission. However, we arrived at the final diagnosis of angioleiomyosarcoma after the operation for the tentative diagnosis of deep vein thrombosis. We removed the firmly engorged deep femoral vein on the second operation. We report here on a case of angioleiomyosarcoma that arose from the deep femoral vein.

Hyperhomocysteinemia is an independent risk factor for cardiovascular, cerebrovascular and peripheral vascular diseases complicated with atherosclerosis and thromboembolism. Increased plasma homocystein level develops from genetic defect of enzyme for homocystein metabolism or vitamine deficiency, has direct toxic effect for vascular endothelium and makes damages to antithrombotic action of vascular endothelial cell. Most of hyperhomocysteinemia is asymptomatic, but rarely develops cardiopulmonary or cerebrovascular accidents. In case of thromboembolism with unknown cause, the hyperhomocysteinemia should be considered as one of the many etiologies. The authors, first in korea, report a case of multiple thromboembolisms of deep vein of lower extremity, pulmonary vessels, superior sagittal and transverse sinus of brain in a patient with the hyperhomocysteinemia with a review of literature.

A ten-year-old female mongrel dog was presented to Veterinary Medical Center, Chungbuk National University with the signs of anorexia, weakness, and hemoglobinuria. Patient had been diagnosed as dirofilariasis based on heartworm antigen test and treated with adulticide (melarsomine) at local hospital one day before admission. On laboratory examinations, there were hypochromic and microcytic regenerative anemia, thrombocytopenia, moderate neutrophilia, and increase ALT, AST, and ALP. Radiographic exam showed main pulmonary artery bulging, pulmonary infiltration and hypervascularity, reduced abdominal serosal detail and mild hepatomegaly. Abdominal ultrasonographic exam showed mild peritoneal effusion and large hyperechoic thrombi at trifurcation of the porta hepatica and the splenic vein. In addition, intraluminal low density area and intravascular filling defect were confirmed on contrast enhanced CT scanning at the same anatomic locations. Patient was treated with anticoagulant and thrombolytic therapy. On day 42 after treatment, complete resolution of thrombi was confirmed via ultrasonography and improvement of clinical signs was observed.

Since the implementation of conjugate Haemophilus influenzae serotype b (Hib) vaccine, the rate of infections caused by Hib has dramatically decreased, and the proportion of infections caused by non-type b H. influenzae has increased. Cerebral venous sinus thrombosis (CVST) is rare; however, it should be considered as a potential complication of bacterial meningitis. Herein, we report about a child who developed CVST after being diagnosed with H. influenzae serotype f meningitis.
